Answer:

Step-by-step explanation:

Given Equation :

$y = \frac{1}{2} x - 3$

Which is in slope intercept form :

$y = mx + b$

Where :

m = slope

b = y-intercept.

Thus , in the given Equation , the y-intercept is -3

ICE Princess25 [194]

We can sort this out in 2 groups. Group 1 has 5 people and each person has 1 granola bar. Group 2 has 5 people and each person has 0 granola bars. Alright , so group 1 has 5 members and each has 5 granola bars, therefore group 1 has altogether 5 granola bars. On the other hand Group 2 has 5 members but with 0 granola bars each. So in result , Group 1 has more granola bars, having 5 and group 2 having 0. Hope this helped!

(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

$\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}$

$\large\textsf{Let's solve for the LEFT SIDE first}$

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

$\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2$

$\large\textsf{Now, let's solve for the RIGHT SIDE last}$

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

$\large\text{NEW EQUATION: 700,000 + \bf 400}$

$\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}$

$\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark$

Find cos x if sin^2x-1/cos x = -1 a. –1 b. 2 c. 1 d. 0

irina1246 [14]

Answer: 1

Step-by-step explanation:

Alright, lets get started.

The given expression is :

$\frac{sin^2x-1}{cosx}=-1$

As per Pythagorean identity,

$sin^2x + cos^2 x = 1$

taking 1 to left side and $cos^2 x$ to right side

$sin^2 x-1=-cos^2x$

Now plugging the value of $sin^2 x-1$ in given expression

$\frac{-cos^2x}{cosx} =-1$

cosx will be cancelled, so

$-cosx=-1$

Multiplying -1 in both sides, it will equal to

$cos x= 1$ ........................ Answer (C)

Hope it will help :)

The right triangle with angle 45 ° has adjacent leg 9 feet
So the opposite leg is calculated from
tan 45 = opposite leg / adjacent leg ⇒ adjacent leg = 9 tan 45 = 9.
That is the distance bc.
The right triangle with angle 60° has adjacent leg 9 and opposite leg (x+9), where x is the distance ab.
Then tan(60) = (x+9) / 9 ⇒x+9 = 9 tan(60)
x + 9 = 15.59
x = 15.59 - 9 = 6.59
Answer: 6.59 feet
